9 Claims. 1

This invention relates to pay roll time calculators wherein the time worked by an employee, even ,though gaps in his time for lunch hours have been had, can readily be ascertained.

It is an object of the present invention to provide a simple hand calculator that can be rested upon the desk of a time clerk and by the simple manipulation of two relatively movable parts, a reading of the total hours worked during the day can be easily reckoned.

According to the invention, a diiferenti-al gear mechanism is connected between a knob and a dial to obtain, when the knob is rotated to register its pointer on a fixed scale an opposite rotation of the dial. When the knob pointer comes to rest on the time at which the employee stopped work a reading of the total hours and fractions thereof can be read on the dial which has been rotated at the index. The fixed dial is held fixed only while the calculation is being made. If it is desired to add to the original hours, hours in the day which have been later worked by the employee, the xed dial bearing the time can be adjusted to register the new starting point with the pointer. Thereafter the pointer is turned to the next stopping point. The new hours will be added to the rst hours and the total hours employed for both workings will now be read on the oppositely rotated scale.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth,

In the accompanying drawing forming a material part of this disclosure:

Fig. 13 is a transverse cross sectional View taken along the line I3-I3 of Fig. 11, looking in the direction lof the arrows thereof.

Referring now to Figs. 1 to 7, description will be made of the first form of the invention wherein I5 indicates a base on which there is stood upright two horizontally spaced supporting members I6 and I1. These members are held in their horizontally spaced relationship at their upper endsv by vertically'spaced spacer bars I8 and I9. The lower ends of the members have outwardly turned flanges 2l which are secured to the base by screws 22.

In the front supporting member there is fitted tightly a bearing sleeve 23 shouldered, as indicated at 2'4, to be inserted through the supporty ing member YI6 from its rear face. This member tion, of the calculator of Fig. 1, viewed along the line 2 2 thereof looking in the direction of its arrows.

Fig. 3 is a detail side elevational view of the main drive shaft.

Fig. 4 is a detail side elevational view of the sleeve relatively rotatable on the main drive shaft having one gear and the rotating dial connected thereto.

Fig. 5 is a side elevational view of the bearing sleeve carried by the frame in which the sleeve shown in Fig. 4 is j ournalled.

, Fig. 6 is a fragmentary face view of the ldials and indicators showing the reading when the pointer has been moved to the stopping time of the worker.

is shown in detail in Fig. 5. The front end of the sleeve 23 has an annular recess 25 adapted to receive a spring lock ring 26. Over the sleeve 23 there is disposed a curved leaf spring 21 bearing against the front face of the member I 6. An external dial 28 is fitted on the sleeve 23 and is held in place after rst compressing the leaf spring 21 and engaging the lock ring 26. The dial 28 is retained in its adjusted position by the spring 21. However, while time is being calculated it remains stationary, the other parts being the only ones moved at this time.

The time dial 28 has a circular recess 3| adapted to receive a rotating dial 32 which is press fitted on a knurled portion 33 (Fig. 4), of a sleeve 35 journalled in the sleeve 23 and hollowed to receive a main drive shaft 38. Keyed to the front end of this drive shaft is a knob 31 having Ia pointer 38 adapted to register with the scale'cn the time dial 28. The opposite end of the shaft is journalled in a bearing sleeve 39 secured to the rear supporting member l1. Im-

mediately in front of the rear supporting member l1 there is xed to the shaft a bevel plate gear "il by a pin 42.

This bevel plate gear 4I forms part of a gear mechanism which includes further 'a bevel pinion G3 pivoted about a vertical axle 'and journalled in the spacer bar I8. This pinion is adapted to be driven by the plate gear 4l as the knob il]Y is turned and drives in an opposite direction fromV nlmatching with the spur gears. The gear dial 12 the plate gear 4I a second plate gear which Vis'- end porti tightly fitted upon a reduced low sleeve 35 to drive sleeve turned.

The time dial '28 (Fig. 1), is marked oi 'ih' twenty-four parts to represent the hours of the day. Starting with twelve midnight at the top of the dial the marks Vare numbered upto twelve noon which will appear at'the bottom of the dial. Beginning from twelve noonthe marks are numbered from one to twelve midnight. The spaces between 'marks can be divided off into fteen mlnute periods. Extending up from the base I5 and secured thereto by the same screws 22 that secure the flange 2l of the'front supporting member I5 therewith, is a transparent member 111 having a pointed upper end 4-8 with an indicating line 9 thereon. Also on this pointed end is a window 51| through which numbers on the rotating dial 32 will appear.

Assuming that the man starts work at twelve oclock midnight the time dial 28 will be adjusted to have the twelve midnight mark on the indicatorline 48. The rotatable dial 32 is numbered from one 'tptwenty-four'"and so indicated with reference to marks ontheperiphery of the same. Between marks there may be smaller marks indicating fractions bf the hour. The rotating dial is aligned with the indicator line 49 so thatits mark 24'wil1 appear through'the window 5 I. The pointer 38 is so arranged in .its connection with the rotating Adial 32' that it will automatically arrive at "the indicator line.

Assuming that the manworks until four oclock the pointer 38 will be turned to the number four on the time dial 28. A reading er four hours will be indicated through lthe window 5| (Fig. 6). Thereafter assuming the manV has had a -rest period of one hour before starting ,workgagaim the time dial 28 will bev adjusted sothat itsA ve oclo'ck mark registers with'the pointer 38. jIf he works from 'five to `seven the pointer will be turned to the seven on the time dial 28 `as illustratedin Fig. 7. These two hours will Vbeadded tojthe original four and a six will'appeai` in the window 5l to indicate the total number "of hours which the man has worked. l

Referring now to the form of the invention shown in Figs. 8, 9 and 10, a "slightly'dlfierent arrangement will be found. Instead of `the inner dial being rotated Aas the knob is turned -the `outer dial is rotated and the reading taken from the same. The entire mechanism is pitched at an angle so that the dials appear on'inclined face.

The entire mechanismi's'husedin a Ycasing 53 having an inclined frontwall -"54. The bottom supports an angularly positioned ueshape'd'x'n-ember 55 in one part of which iis journalled'a pinion 5e and in the other part of whioht'here is jour-'- nalled a shaft`51. This shaft ha'saplate 'g'ar 'connected to it by a pin 59. 'me forward eric or the shaft has a pointeratwicnismoveuny a handle projection "62. As thepoint'er'is adjusted on ofhbllA 35 and the rtating dial in a reverse direction from which vthe knob is is accordingly held centered by the spur gears 1| jrnalled 'to the plate 68. A nnal cover plate '13lliaving'an hpening 14 extends over the spur ,gears andthe toothed dial. The dial 12 is set to an indicator mark 15 by grasping'and moving one of its handles 16.

Pointer 6l is grasped Iby :its handle 62 and turned tc the. time when the employee stops work. By illustration the indicator Y 6 lA has been moved -to flour gclo'ck on'the innerV dial. Through the window 61 therewill appear the number ofhou-rs which Vtheenployee has worked :from twelveat mgntfto four ociock in the mornin-g. :This ninnberwill be four. VAdded hours can -be calculated by"adjusting the parts in the'same manner as the parts 'of' the -rst form were adjusted.
